Vulnerability discussion

Log data is essential in the investigation of events. If log data were to become compromised, then competent forensic analysis and discovery of the true source of potentially malicious system activity would be difficult, if not impossible, to achieve. In addition, access to log records provides information an attacker could potentially use to their advantage since each event record might contain communication ports, protocols, services, trust relationships, user names, etc.

Check content

At the command prompt, execute the following command: ls -la /var/log/vmware/vcac/vcac-config.log If the log file has permissions more permissive than "640", this is a finding.

Fix text

At the command prompt, execute the following command: sed -i "/^[^#]*UMASK/ c\UMASK 077" /etc/login.defs

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
